Figure 4-2 Foam bars<br />
The foam bars (order code 3122 785 90580 for two pieces) can<br />
be used for all types and sizes of Flat <strong>TV</strong>s. See figure “Foam<br />
bars” for details. Sets with a display of 42” and larger, require<br />
four foam bars [1]. Ensure that the foam bars are always<br />
supporting the cabinet and never only the display.<br />
Caution: Failure to follow these guidelines can seriously<br />
damage the display!<br />
By laying the <strong>TV</strong> face down on the (ESD protective) foam bars,<br />
a stable situation is created to perform measurements and<br />
alignments. By placing a mirror under the <strong>TV</strong>, you can monitor<br />
the screen.<br />

Figure 4-3 Aluminium stands (drawing of MkI)<br />
The new MkII aluminium stands (not on drawing) with order<br />
code 3122 785 90690, can also be used to do measurements,<br />
alignments, and duration tests. The stands can be<br />
(dis)mounted quick and easy by means of sliding them in/out<br />
the "mushrooms" (not valid for all models!). The new stands are<br />
backwards compatible with the earlier models.<br />
Important: For (older) F<strong>TV</strong> sets without these "mushrooms", it<br />
is obligatory to use the provided screws, otherwise it is possible<br />
to damage the monitor inside!
